The presence of animals in human life is invaluable. Pets can serve as working animals or companion animals. The research on human-animal interaction is relatively scarce, but the already available data proposes that animals help people increase fitness levels, reduce stress and bring happiness. Different species can play different roles in human lives. They can help with certain conditions as well. Dogs can help increase exercise and activity levels and fish can induce calmness. The increase in exercise can reduce blood pressure, cholesterol levels, and triglyceride levels and improve heart health. Pets help to reduce subjective psychological stress factors such as fear and anxiety.

Animals are usually innately mindful. It means that they are attentive with good intention, compassion and awareness. Due to these qualities, they increase autonomy, self-concept and self-esteem in very young children. Dogs can help children with Attention-deficit/hyperactivity disorder (ADHD). Not only can they help these children with their concentration, but also with their confidence and responsibilities. They help children build their emotional and social skills. Pets help humans release natural feel-good hormones like serotonin and oxytocin and reduce the levels of stress releasing hormones like cortisol. This leaves a person feeling free of anxiety, tension and depression. They are live mood enhancers and have a way of curing loneliness. While more and more research continues to take place in this area, one thing has been established i.e; pets have beneficial impacts on human health both physically and mentally.
